'IMPROVEMENT 1N HAsP ron rum-Locks.

The Schedule refen'ed to in these Letters Patent and. part of the sam.

To allfwhom 'it may concern:l

,position .Figure 2, a vertical section on the dotted line of lig. 1, bui-,showing thefhasp in its pendent position;

' Figure `3, a front view of the lock Without the hasp, and having the covering-case or cap removed, in order to display its tumbler, bolt, Sac.; and

4Figure 4, a transverse section of th/c hasp and covering-cap, as when the former is closed down upon the latter..

Like letters of 4reference indicating the same parts when in the different figures. v

The' object of my improvement is to produce a more strong and secure self-locking tumbler-lock, of that. class which docs not require a recess or hole to be made in the Wall of the trunkfor the reception of either the.

hey, the covering-cap, or the tumbler andbolt.

' My invention consists in the construction, arrange; ment, and combination of the diiierent parts,.as hercinafter described and specified.

Referring to the drawings', Ais the'foundation-plate of the lock, B the hasp, C the case orcap, D the bolt, and E the tumbler. .i

The inner.or rear. side of' the plate A is plain, or without any proj ections,-and therefore lies evenly and closely against the front wall of the trunk, when fastv cned thereto by throughrivetsfin the usual manner. The bolt D and tumbler E ,turn on their respective pivots, d and e', whereby they are secured .to the hout side ofthe plate A, in the vrelative positions as shown in fig. 3. They-are connected together at their lower ends by a curved spring, F, so that the latter con# .stantly tends to throw the upper end of the bolt D across the hole, c', of the cap, C, which is applied and secured over the bolt and tumbler, as shown in g. 1, and at the same time to throw the head, e, of the tumbler E,down behind the stop d of the bolt D, and thus cause. the upper end of the bolt D to enter the staple b of thehasp, when .the latter is pressed, by hand, into the said hole c. Directly under the hole c there is a curved spring, G, fixed to the plate A, so as to bear automatically against the under side of the cap, C, but also so as tor-yield inward to the pressure of thestaple b', when the trunk is in the unlocked condition, the said spring G, in that case, preventing the upper end of the bolt D-rom being sprung across `the said hole, as representedin figs. 2 and 3.

The bolt D and' tumbler E are brought into' the positions shown in fig. 3 by turning, in either direction, the usual key.

The hasp B is hinged to the upper ends of two ribs, b b, fast on the front' side of plate b, and shuts down flush between said ribs b, and is thus held firmly in place; and on the sides of the swinging end of the hasp B there are two fixed anges, b'4 b, which t closely against the. respective sides, c" d', of the case C, when the hasp is pressed down closely upon the former, and -thus prevent the staple b1 from being broken off by the rough handling of the trunk in transportation.

The plate b has two or more rivet-holes, b5, between the ribs b" b, whereby it is to be riveted fast to the lid of the trunk. v

The upper part ofthe plate A has also one or more rivet-holes, a, just above the case 0, whereby the plate A is to be mainly riveted fast to the body of the trunk, and thus, like the rivets b5, be covered, and securely protected from being cut on", when the hasp B Vis closed down and locked.

Whei`1'the trunk is'unlocked, the tumbler E, bolt D, and' spring G, will be in positions shown in gs. 2 and 3, and consequently, when the spring G is pressed in by means of the staple b of the hasp B, it willrelease the bolt D, and allow it to be sprung into the staple, v and thus lock the' trunk. The key is indispensable to lift the tumbler E and turn back the `bolt D, (see g. 3,) when the spring G reacts, and throws out the hasp B to the position shown in iig. 2. 'It will therefore be seen, that 'this is a self-locldng tumbler-lock; that its application does not require the face-,side Aof the trunk to be cut into, and that the flanges bi b, on the sides of the swinging end of the hasp, will, when the trunk is locked, itclosely along the respeetiye sides of the case C, and thus secureA both the staple b1 and bolt D, from being broken oif or strained, by the rough handling to which the trunks of travellers are subjected; and, moreover, the rivets at a. and bwill be covered by the hasp, and therefore inaccessible for vremoving the lock or staple, when the trunk is locked, and that, by turning the key either toward the right or toward the left, will unlock the lock.

Having thus hilly descn'bed my improved trunk-lock,

What I claimV as new, and desire to secure by Let- .ters Patent, is confined to the following, viz:

Hinging the swinging hasp -B tothe upper edge of its plate b', so that it can be freely turned suiiciently upward to allow the plate b to be fastened to the trunk-lid by rivets b5, which will be covered by the said hasp when the trunk is closed and locked, substantially as andfor the purpose set forth and described.
